Watercress is a leafy green plant that usually grows in the water of natural springs. It belongs to the family of cruciferous plants, including arugula, kale, Brussels sprouts, and broccoli. This water vegetable is one of the ancient greens which might have also been a part of the Roman soldiers’ diet. It was not just a garnish if seen historically but was considered a superfood.
Watercress is also known as the Yellowcress or by its botanical name Nasturtium Officinale. It is an aquatic flowering plant. The plant is native to Asia and Europe and grows very rapidly.
These plants grow in the form of bushy colonies, and they root through their stems freely. The flowers of watercress grow in the form of clusters of tiny white flowers with four petals each. The leaves of watercress grow alternately and are pinnately compound in structure, and usually bear three to nine leaflets at once. The seedpod of watercress is called a “silique,” and each silique bears only two rows of seed. The stems of watercress are hollow that makes them float over water. And the flower clusters of watercress are visited by insects like hoverflies frequently.
Because of the rapid growth and widely adaptable nature of watercress, it is considered a weed in several regions of the world. While in some other regions, it is regarded as an aquatic vegetable or water vegetable. This plant widely grows in several locations all around the world.
In 1808, William Bradbery, a horticulturist, introduced this aquatic vegetable in the United Kingdom and cultivated it commercially. In the United Kingdom, Watercress was first grown alongside the Ebbsfleet River in Kent. But, today, watercress is grown in several counties of the UK. The counties which are the most notable for the growth of watercress include Hertfordshire, Hampshire, Wiltshire, and Dorset.
Alresford, a town near Winchester, holds a Watercress Festival annually. Around 15,000 visitors come to this festival, and there is also a preserved steam railway line named after this local crop. In the 1940s, Huntsville and Alabama of the United States were locally known as “Watercress capitals of the world.”
Along with being edible, watercress also carries a lot of minerals and vitamins. Its flavor is mildly hot mustard-like. It is used as a food in several ways, for example:
- Salads and sandwiches
- It is cooked as a potherb
- Smoothies and soups
- Used to flavor dressings and sauces
- The seeds of watercress are ground to a powder to be used as a mustard
Watercress is considered a superfood due to the health benefits that can be attained by eating it. This water vegetable only consists of 4 calories per 34 grams. Moreover, watercress is a nutrient-dense food. Watercress is also ranked as number one in the list of Powerhouse Fruits and Vegetables by the US Centers for Disease Control.
Watercress has high amounts of antioxidants (components inhibiting oxidation). In humans,oxidative stress is usually associated with chronic diseases, such as diabetes, cardiovascular diseases, and cancer. And watercress being highly packed with antioxidants can help avoid and protect from oxidative stress and lower the risk of such chronic illnesses. Moreover, watercress may also help lower cholesterol levels.
